High Flow Tetpor HT
HIGH FLOW TETPOR H.T. gas sterilisation filter cartridges provide unrivalled performance in process industry applications where continuous cartridge operation of up to 100 °C (212 °F) is a requirement. Applications include specific biological fermentations which use high inlet air temperatures and heated vent filters on storage tanks whose contents are at elevated temperatures >80 °C (176 °F), e.g. WFI tanks.
HIGH FLOW TETPOR H.T. cartridges utilise a proven inherently hydrophobic, expanded PTFE membrane with an absolute removal rating of 0.01 micron. This ensures the removal of all airborne bacteria, viruses, and bacteriophage. Nomex membrane support layers facilitate continuous operation at temperatures up to 100 °C (212 °F).

Recommended Operating Conditions
The maximum differential pressure in direction of flow (outside to in) is 3.5 barg (50.76 psig) at 100 °C (212 °F). The maximum recommended continuous operating temperature is 100 °C (212 °F).
Effective Filtration Area (EFA)
10” (250 mm): 0.9 m² (9.8 ft²)
Sterilisation
HIGH FLOW TETPOR H.T. cartridges can be in situ steam sterilised for up to 120 cycles at 142 °C (287.6 °F).
Retention Characteristics
HIGH FLOW TETPOR H.T. cartridges have been fully validated as sterilising grade filter cartridges for compressed air and gas applications. They exceed liquid bacterial challenge levels as recommended by ASTM+. In addition, HIGH FLOW TETPOR H.T. is further validated by aerosol bacterial challenge testing.
+ASTM American Society for Testing and Materials
Integrity Test Data
All cartridges are integrity tested prior to despatch by the pressure decay and aerosol challenge test methods. Values are for cartridges wetted with 60 / 40 IPA / Water.
